Patented Oct. 22, 194@ UNITED STATES PATENT OFFICE CABLE socKET y Fred N. Osl'nun, HoustongTex, Application' Maren 1v, 193s, Aserial No. 196,377- r 1 claim. (o1. 25a- 26) This invention relates to a cable socket.A

It is an object of the invention to provide a cable socket by means of which a cable, or operating line, may be attached to a swab, or other 6 tool, in a well and which is of such construction that it may be removed in ywhole or at least in part-from the cable when it is desiredv toremove the cable from the crown block sheaves or'other sheaves over whichthe cable operates and then W ire-attached to the cable forsuccessive use.

At the present time in the use of an operating cable when it is desired'to detach the cable from the operated tool and to remove the vcable from the sheaves over which it operates, as for l example when it is desired upon comple-tion of a job to move to another, the cable socket, employed for attaching the cable to the tool to be operated, is detached from the too-l and the cable is severed to detach the socket therefrom :u for the reason that the socket will not pass through the sheaves and, if attached to the cable, the cable can not be detached from the sheaves. This necessitates the attaching of a new socket to the end of the cable when it is desired to again 5 use the cable for carrying on the work.

It is an object of this invention to provide a novel type of socket that may be wholly or at least in part removed from the cable so that the cable Will pass through the sheaves and the socket is of such construction that the removed parts may be readily re-attached to, or reassembled on, the cable without the necessity of severing the cable or loss of material or parts, thus greatly facilitating the work.

215 With the above and other objects in view, the invention has particular relation to certain novel features of construction and arrangement of parts and use, examples of which are given in this speciiication and illustrated in the accomau panying drawing, wherein:

Figure l shows a side elevational view of the socket attached to the cable and to the tool to be operated.

Figure 2 shows a side elevation thereof partly 4.3 in section, taken at right angles to the view shown in Figure 1, and

Figure 3 shows a longitudinal sectional view of another embodiment. l

Referring now more `particularly to the drawm) ing wherein like numerals of reference designate the same parts in each of the figures, the nul meral I designtes an outer tubular jacket whose lower end is' formed with an internally threaded box 2 to receive the externally threaded pin 3 55 of the tool 4 to be operated. In the present instance this tool is a swab, to -be operated in the well casingy 5; although the socket is adapted to be attached to,y any type of well' tool to be operated in the well'.` v

Fitted within the shell I there isthenipple 6 of a cylindrical'external contourfandwhich is provided With-the internal downwardly `flared bore 'I'. Fitted loosely in thef'jacket above said nipple there isan annular anitiirictionA thrust ring 8 preferably formed of hard metal. The lower end of ther guard .sleeveS is screwed into the upper end of .the jacketI. 'The upper end of this sleeve v.is` formedwi'th theexternal downwardly pitched ratchet teeth III for engagement with the shing tool in case the cable should break and the socket drop into the well and must be fished out. The sleeve 9 is split longitudinally into two halves as shown in Figure 2.

In assembly the thrust ring 8 is slipped over the free end of the cable II and said free end of the cable is then inserted into the nipple 6 and melted babbitt, or similar metal, is then poured into the socket 'I around the cable end and allowed to harden.' The nipple 6 and the thrust ring 8 are then inserted into the jacket I and the sections of the sleeve 9 are assembled around the cable and screwed into the upper end of the jacket and thus completing the assembly.

When it is desired tov remove the cable from the sheaves over which it operates, the socket may be detached from the pin 3 and the sleeve 9 unscrewed from the jacket I and removed from the cable and the jacket then detached leaving only the nipple 6 and thrust ring 8 on the cable end and these will readily passI through the sheaves and permit the removal of the cable.

In the embodiment shown in Figure 3 there is the outer jacket Ia which is formed of sections screwed together, the lower section Ib forming the box member.

Within the jacket Ia'there is the tubular nipple I3 which has the internal bore I4. This bore has its upper end reduced in inside diameter forming the inside upwardly tapering shoulder I5. The nipple I3 has its upper end reduced in outside diameter forming the outside upwardly tapering shoulder I6 thereon.

Within the jacket Ia and itted around the upper end of the nipple I3 there is a collar I1 whose lower end hasV the inside outwardly ilared face I8 which rides on the shoulder I6. Between the upper .end ofthe collar I'I and an inside annular shoulder I9 of the jacket Ia there is a thrust ring 8a preferably formed of hard mate-` rial. In this embodiment the nipple I3a is split longitudinally in two halves as shown in Figure 3 and the upper end of the jacket la is extended upwardly and reduced in external diameter providing the tubular neck 20 which has the external ratchet teeth I0 for the purpose above stated.

In assembling this type of socket, the jacket Ia, with the box Ib removed, may be slipped over the end of the cable Iliand the thrust ring 8a, the collar II and the sections of the nipple I 3a may then be assembled around said cable end and melted babbitt, or similar material 6a,

may then be poured into the nipple I3 around the.

cable end and allowed to harden. 'I'he jacket Ia may then be lowered until the shoulder I9 rests on the thrust ring 8a and the socket member Ib may then be screwed into the lower end of the jacket I a completing the assembly as shown in Figure 3.

When it is desired to detach the socket from the table preparatory to removing the table from the sheaves, the socket member Ib may be detached from the jacket Ia and said jacket Ia then moved upwardly on the cable to expose the parts 8a, I'I and I3. 'I'he two halves of the nipple I3 may then be detached from the babbitt 6a and the collar I'I and thrust ring 8a then slipped off over said babbitt leaving only the babbitt 6a on the end of the cable and this will readily pass through the sheaves. Y

j When it is desired to reassemble the socket on to the cable, the jacket I a with the box member Ib removed may be slipped over the cable end -and the thrust ring 3a and collar I1 likewise slipped over the cable end and the two halves of the nipple I3 may then be iltted around the babbitt and the upper end of said nipple inserted into the collar I I and the box member Ib may then be screwed into place in the lower end of the jacket Ia, thus completing the assembly.

The drawing and description disclose what are now considered to be preferred forms of the invention by way of illustration only while the broad principle of the invention will be defined by the appended claim.

What I claim is:

A cable socket comprising an outer jacket formed of sections screwed together, the lower section forming a box member, a longitudinally sectioned tubular nipple within the jacket whose lower end is extended into the box member, said nipple having an internal bore whose upper end is reduced in inside diameter forming an inside shoulder, the upper end of the nipple having its outside diameter reduced forming an external shoulder which is tapered, a collar within the jacket fitted around the reduced end of the nipple and whose lower end conforms to and abuts said external shoulder, said jacket having' an inside, downwardly facing shoulder, a wear ring between the collar and the downwardly facing shoulder, a soft metal filling the nipple from end to end and molded about an end of a cable extended into the nipple, the diameter of said
